Question

Find the distance between points M(-1,-10) and (-12,-3). round to the nearest tenth

Answer 1

The formula of the distance between two points:

`d=√((x_2-x_1)^2+(y_2-y_1)^2)`

We have the points (-1, -10) and (-12, -3). Substitute:

`d=√((-12-(-1))^2+(-3-(-10))^2)=√((-11)^2+7^2)=√(121+49)=√(170)`

`√(170)\approx13.04`

Answer: d ≈ 13.0
